SELLEY, a citizen of the linited, States; residing at Nashville;inthecounty of l):u"idson 5 and Stnto of 'lennesseei, hare invented newand useful Improvementsjin Scales, of ivhieh.

lhe invention reln-tes gmerullr to an iniproven ent-Iin $('.i llQS;1I1:1(i pttl'tiflllliu'hv it) en xo automatic Qoinputing scnledesigned for accuretely determining the weight of any artieles placedupon the scale pan.

- e The inn-m object of the present invention is the production. of in;scale of the tr m described wherein the weight of: the article supported on. these-ale pan is directlytransmit.- tedto and serves torevolve a shaft with the eil'ectto move a pointer, orindieiitor over afixed settle strip. e ,e

Another obj ect of the'invention is the pro duction of means wherebyequilibrium of the 'lnoveblepzu'ts of the scale is quickly gained afterthe depositof the i 1.rticle on the scale Hill, the constructionpror-iding against; vi-

Theeasing forms a. fixed housing for the op -1-.mting parts, beingpreferably supported- 0. upon legs 4 or in anyother convenient mim--I\er. The inner surfaces of the heads 3 are centrally formed withhearings 5; of thepnr tie'uler type to he hereinafter noted, Revohihl ysupported within the hearings 5 is what Figurel is averticaleentrgltransverse see- I term the scale drum,eon1pri'sing a. shaft 6" theinterior diameter of the casing. disk 18 formed on the inner surl'ucewith n- ,v.' e I, formed at its nds with iTllHlHOllS": lul' cuo'ierntioii with the ri' spective bearings and provided near eachtrunnion with =1 disk 8, in'eferebly (\l ':ttlifllt'iUi-Pl sounwllu-lless the-n Ettt'll centrally arranged-t-oncentrieprojection t), u

The scale pain 13 is thus pendent below and forward ofthorns-ins. and provides against undue vibration ol' the parts under theinliuencc of an article deposited upon the pen.

The cylindrical strip "2 is provided in its forward portion withcirctnul'tn'eutinlllv erranged slots-15, hppi'is-ite the edges-"oi thedisks 8, and'of'e length to accord with'the maximum movennni t of thesonic) .A- sen-lei also slotted at 1.7 to coirespond end registe withthe slots 15. An inoicntoi' 'or pointeris secured to the edges of thedisks' saidtween the pointerand disk, as screws 19, pro-e strip 16 isSOOUI'GtihO the time of the. casing- 1nclud1ng the slots 15, szndsrnlestriplming ieeting through the respective slots 15 in the easing, Thedrum is providedwith a e un-L s to ' weights .20 being preferably induplicate and tel-poise 20, preferablyin the'form of disk-- like weightssecured to the normally lower edge of one .of the disks by a bolt21,.said

securedupon opposite sides of the disk. By this cons'trii'ction the maincounterpoise is readily removable -when desired. One or both ofthe disksare further rovidedwith 'a counterpoise 22 to counterba ance the weightof the ointerand securing means. Pendent from t e normally rear portionof one of the I disks is a rod 23, also operative-through an desiredform ofweight' ho (her 25, to provide. for thereception of additionalWei hts in'the openin' in the casing and a sleeve: 24 as in the sea epan supporting means. The free lower end'of the rod 23 is" rovided withany event-it is desired to increase t e normal maximum capacity of thescale.

The scale stri'p'16 is provided onits outer surface with a series ofcharacters to indicate the weightjof the article supported onthe pan iIIPOIIIidS and ounces and to simultaneously indicate the price of sucharticle at varying amounts per pound. To provide for this result thestrip is divided into a column 30 at one side of one of the'slots 17therein and said columndivided by a series of transverse lines intoounces and ounds, and between the slot 17 the strip is dividedinto aseries of vertical columns-3'1 bearin at their heads a price'ai'nountper pound,eac column further divided' in accordance with the division ofthe weight column, and each bein of said divisions in theprice-column'are'to be inscribed with an amount determined. by the number of oundsalined with -said particular space at t e'price per oundnoted at'thehead of the-"columnthe ointer'is' in effect an 'indicator-stri j reac gwholly across the coin utiii'g section ofthe strip, it is obvious thattli will register with thetotal price. or, the, article bein weighed atany iven price perpound, while the end of the pointeroverlying'l'thepound divisions will indicate in pounds and ouncestheweight ofthe article.

If desired the peripheral edge of the disks I 8 at the portionnorinally'in diametrically opposed relation to thescale strip lfimayjbe" provided with a scale strip '26, indicatingpounds and ounces withthe particularin'di-I 'cating mark visible through the opening 27 formedin the rear portion'of the casing, so

that the amount in icatedon the scale may be visible fro'm'both sidesthereof. The scale strip 15 is fpreferably housed by anoverlying plate28 0 transparent material, whereby to protect the operating-part in anobviousman ner.

The operation of the device will be fully apparent from the constructiondescribed, it being noted that the sleei e's 14 'are'sha ed to preventvibration of the scale pan incir ent to I the deposit-of an articletlieron,-so that the particular colum'n may be readily found by means ofthe pointer .Withoutregard to th' 1' copper edge of said counter'nection to, the

support connected with the memlie additional, weight carrier dependingfr scale willquickly reach a set position after the deposit of thearticle. In the normal position of t the straps -10, they are partiallywound about the strap disks 9, and therefore as said straps unwind inthe weighing movement of the drum, they increase the weight in favor ofthe scale pan. As such increase interferes with the accuracy of thescaleprovision is made to counteract it by recessing the scaledisks 9immediately adjacent the connection of the straps 10. thereto, as shown.at 29. The material thus cut from the strap disk will provide a slightexcess weight favoring the diametrically opposed portion of the disk,thus counterbalancing the extra weight. provided in the unwinding of thestraps.

Thepointer 18 is divided by a series of transverse lines to providecolumns register-- ing with the price columns on the scale strip,'

and iiithese columns on the pointer ismarked a price mark correspondingto the pricemaik at the head of the registering column oi 'the scalestrip, The pointerthus providesfaiid carries a price per pound table, sotliatigthe price mark at the head of the columns of th" scale strip; gHavin thus described the invention whatis'claime' as new,is:- 1.'
